Is Coarticulation in Speech Kinematics Centrally Planned?

Coarticulation in speech production is a phenomenon in which the articulator movements for a given speech sound vary systematically with the surrounding sounds and their associated movements. Although these variations may appear to be centrally planned, without explicit models of the speech articulators, the kinematic patterns which are attributable to central control cannot be distinguished from those which arise due to dynamics and are not represented in the underlying control signals. In the present paper, we address the origins of coarticulation by comparing the results of empirical and modeling studies of jaw motion in speech.
